John Gruber illustrates the dangers of not having a clue about history: "The utter simplicity of the iOS home screen is Apple's innovation. It's the simplest, most obvious 'system' ever designed." Thanks for playing.

One could argue that the Psion 3a had a fairly icon/text in a grid style layout (if one was going to be very pedantic.) But the icons in a Window was what Mac OS was doing in 1984, so who copied whom? I'm guessing Xerox possibly had something similar? It depends where you decide innovation and design originate in this specific area.
